Product Details

In developing the SC11S1 Marantz engineers took as much as possible from the Reference Series SC7S2. For example, the full balanced layout in-current feedback technology was applied, guaranteeing excellent signal integrity. Then the Wolfson high linear electric volume control and the new version of small signal amplifier HDAM ? specially developed by Marantz ? were added. The unit now incorporates the HDAM-SA2, which guarantees precision high-speed signal handling over a wide frequency range. It also uses high precision Melf resistors to minimise tolerances ? essential for audio integrity. While the high quality in-current feedback phono amplifier for the MM/MC system makes external phono amplifier obsolete. And for advanced systems the floating control bus allows bi-amp and multi-channel set-ups. It all adds up to a scintillating audio experience with crystal clear transparency

Choke-Input



Choke Input


In the power supply section, the choke input topology is adopted to drastically reduce rectifier harmonic noise and to reduce the influence of distortion from the mains power network. This system is especially suitable for a control amplifier in which very small signal amplification occurs.

Copper-Plated-Diecast-Chassis



Copper Plated Diecast Chassis


A copper plated chassis provides the best shielding against noise or electromagnetic distortion radiating from other components in the equipment. It prevents this noise from being amplified together with the audio signal. And even more important, it gives equal low impedance ground level to every point of the chassis, keeping the ground potential as clean as possible.

customized_components



Customized Components


On paper an electrical component might look excellent but the result may fall short of the combined design expectations. Marantz selects the appropriate components for the specific design application. In some cases it's simply not possible to use standard components that meet the high Marantz standards. These components will then be specially made for Marantz in close cooperation with the Marantz engineers.

HDAM-SA



HDAM SA


Marantz developed its own discrete circuit boards to replace standard IC's. These HDAM's consists of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound. Over the years Marantz developed different types of the HDAM to improve quality and to fit to the special requirements of a product category like CD or amplifier.

Linear-Volume-Control



Linear Volume Control


Linear volume control offers minimal cross talk with a very precise volume adjustment over a range from 0dB to 100dB with a gang error less than +/- 0.5dB.

pure_source_direct_audio_ex



Pure / Source Direct / Audio EX(clusive)


Pure / Source Direct / Audio EX are special listening modes that provide the highest possible signal purity. They can be used for both analogue and digital sources, with two-channel or multi-channel inputs. When selected, the signal follows the most direct path not passing the tone and bass management circuitry or any DSP (digital signal processor) of AV Receiver or on players pitch control, digital output or the display will be switched off. The less processing and functionalities the closer the signal is to the original, the less it is distorted.

Shottky-Diodes



Shottky Diodes


A Shottky diode is a special type of diode with a very low forward-voltage drop compared to normal diodes. This lower voltage drop translates into higher system efficiency. Shottky diodes have very fast signal handling, can easily stay higher temperatures and are sensitive very low voltages.

symmetrical_circuit_layout



Symmetrical Circuit Layout


To achieve the best possible sonic performance, signal paths need to be short, direct and mirror imaged. The construction of our circuitry provides improved stereo imaging by ensuring close to perfect symmetry between right and left channel layout.

toroidal_transformer



Toroidal Transformer


Toroidal transformer has several advantages over a normal EI core transformer. It is very efficient and therefore delivers more power compared to the same size of an EI core transformer. In addition, due to its shape, the electromagnetic radiation and the mechanical vibration are extremely low all ending in a better sound quality.
